Abstract

A method for processing an incoming call in the middle of using a handsfree device in a mobile terminal is provided to conveniently, safely, and selectively identify a caller according to a user's operation for pressing the SEND button short or long in case a call is received in the middle of using a handsfree device. In the middle of executing a handsfree call, the control part of a mobile terminal detects a signal inputted through a jack connection part and checks whether a handsfree button is inputted(301). If the handsfree button is inputted, the control part checks whether a new call is received(303). If a new call has been received, the control part checks whether the handsfree button is inputted during more than a preset time(307). In case the handsfree button is inputted during more than the preset time, the control part checks whether the caller number of the incoming call is registered in the phone book(311). If the caller number is registered in the phone book, the control part reproduces the caller's name, registered in the phone book, by voice and outputs it to the handsfree device(315). Then, the control part checks whether the handsfree button is inputted during more than a preset time(317). If the handsfree button is inputted during more than the preset time, the control part forms a speech path to the new incoming call(321).

In the following description, the mobile communication terminal includes a cellular phone, a personal communication system (PCS), a personal data assistant (PDA), an international mobile communication-2000 (IMT2000) terminal, and the like. The following description will be described with the general configuration of the above examples.

Referring to FIG. 2, a modem controller (eg, an MSM chip) 200 controls the overall operation of the mobile communication terminal. For example, it performs processing and control for voice call and data communication. Although not shown, the modem controller 200 includes a central processing unit (CPU), a CDMA core, a vocoder, an internal codec, and the like.

Here, the CPU controls the input / output signals of the display unit 203 and the key input unit 202 and the voice input / output of the microphone and the earphone. The CDMA core channel-codes and spreads data (for example, data from the vocoder) to be transmitted for Code Division Multiple Access (CDMA) communication, and performs a base band analog (BBA). And the baseband signal from the baseband processor 206 is despreaded and channel decoded to restore original data.

The vocoder is a voice coder, which extracts only a voice feature from PCM data generated through the internal codec and converts it to another data rate (for example, 8.6 Kbps, 4.0 Kbps, 2.0 Kbps, 0.8 Kbps, etc.). do. The internal codec converts the PCM data from the vocoder into an analog voice signal and transmits it through a speaker (not shown), and converts the voice signal received through a microphone (not shown) into PCM data and provides the vocoder to the vocoder. It performs the function. In addition, the internal codec includes a module (or a function) for converting text into voice, and according to the present invention, the jack connection unit 208 synthesizes the caller's information (name or telephone number) into a voice signal during a hands-free call. Output to the ear microphone 208 through. As another example, the module for converting the text into the voice may be implemented in the external codec 204, or in another example, may be implemented as a separate device.

The memory 201 includes a program memory, a data memory, a nonvolatile memory, and the like. The program memory stores a program for controlling the overall operation of the mobile communication terminal. The program memory may use a flash memory. The data memory temporarily stores data generated during the operation of the wireless telephone. The data memory may use random access memory (RAM). The nonvolatile memory stores telephone numbers and system parameters registered to perform functions such as speed dialing. The nonvolatile memory may use an EEPROM.

The key pad 202 is composed of 0 to 9 numeric key buttons, a menu button, a cancel button, a confirm button, a call button TALK, an end button END, and an internet access button. And a plurality of function keys such as navigation key buttons, and provide key input data corresponding to a key pressed by the user to the modem controller 200. The display unit 203 displays status information generated during the operation of the mobile communication terminal, a limited number of characters, a large amount of video and still images, and the like. The display unit 203 may use a liquid crystal display (LCD).

The codec (Coder-Decoder) 204 connected to the modem controller 200 is a codec for playing music files (eg, MP3 files, music files downloaded from the Internet). The codec 204 decompresses a music file (for example, an MP3 file) from the memory 201, reproduces the audio file as an analog audio signal, and outputs the analog file to the ear microphone 208 through the jack connection unit 207. As an example, the codec 204 may be a moving picture expert group (MPEG) -1 audio layer-3 (MP3) player.

The RF module 205 lowers a radio frequency (RF) signal received through an antenna to provide the baseband processor 206 with a frequency down, and transmits the baseband signal from the baseband processor 206 to a frequency. Up to transmit through the antenna. The baseband processing unit 206 converts the baseband analog signal from the RF module 205 into a digital signal and provides the digital signal to the modem controller 200, and converts the baseband digital signal from the modem controller 200 into an analog signal. The signal is converted into a signal and provided to the RF module 205.

On the other hand, during a call or music listening using the ear microphone device 208, the audio output path is formed of the earphone and the microphone (not shown) of the ear microphone device 208 connected to the jack connection unit 207 instead of the speaker and the microphone. do. The jack connection unit 207 detects a connection of the ear microphone device 208 and a button operation of the ear microphone device 208 and outputs the detected button operation to the modem controller 200.

Referring to FIG. 3, during a hand-free call, the controller 200 detects a signal input through the jack connection unit 207 in step 301 and checks whether a hand-free button (eg, a call button of an ear microphone) is input. . When the hand free button is input, the controller 200 checks whether a new call is received in step 303. If the new call is received, the flow proceeds to step 307, otherwise the flow proceeds to step 305 to terminate the call.

In operation 307, the controller 200 determines whether the hand free button is input for a set time or longer. If the hand free button is input for less than the set time, the controller 200 proceeds to step 321 to form a call path with a call currently waiting, and returns to step 301 to perform the following steps again. If the hand free button is input for more than a predetermined time, the controller 200 proceeds to step 311 and checks whether the caller number (phone number) of the incoming call is registered in a phone book.

If the caller ID of the incoming call is not registered in the phone book, the controller 200 reproduces the caller ID by voice in step 313 and outputs it to a handfree device (eg, an ear microphone). Proceed to If the caller number of the incoming call is registered in the phone book, the controller 200 reproduces the name of the caller registered in the phonebook as a voice and outputs it to the handfree device in step 317. Proceed to

As described above, after the caller information is output as a voice, the controller 200 checks whether the hand free button is input in step 317. When the hand free button is input, the controller 200 checks whether the hand free button is input for a set time or more in step 319. If less than the predetermined time is input, the controller 200 returns to step 301 to perform the following steps again. In other words, it keeps the existing currency. If more than the predetermined time is input, the controller 200 proceeds to step 321 to form a call path with a call currently waiting, and returns to step 301 to perform the following steps again.

In the above-described embodiment, when the voice output of the caller information is selected, the caller information is output as voice while maintaining an existing call. As another example, when the voice output of the caller information is selected, the call may be output after the existing call is paused. In this case, since the caller information is output after temporarily disconnecting the call, the user can hear the caller's information more clearly.

4 is a flowchart illustrating a procedure for processing an incoming signal during music reproduction using a hand free in a mobile communication terminal according to another embodiment of the present invention.

Referring to FIG. 4, during music playback, the controller 200 detects a signal input through the jack connection unit 207 in step 401 and checks whether a hand free button (eg, a call button of an ear microphone) is input. When the hand free button is input, the controller 200 checks whether a new call is received in step 403. If the new call is received, the process proceeds to step 407. Otherwise, the process proceeds to step 405 to end the music playback.

In operation 407, the controller 200 checks whether the hand free button is input for a preset time or longer. If the hand-free button is input for less than the set time, the controller 200 proceeds to step 423 to form a call path with the incoming call and ends the present algorithm. If the hand-free button is input for more than a preset time, the controller 200 proceeds to step 409 and pauses music playback.

In step 411, the controller 200 checks whether a caller number (phone number) of the incoming call is registered in a phone book. If the caller ID of the incoming call is not registered in the phonebook, the controller 200 reproduces the caller ID by voice in step 413 and outputs it to a handfree device (eg, an ear microphone). Proceed to If the caller ID of the incoming call is registered in the phone book, the controller 200 reproduces the name of the caller registered in the phonebook as a voice and outputs it to the handfree device in step 417. Proceed to

As described above, after the caller information is output as a voice, the controller 200 checks whether the hand free button is input in step 417. When the hand free button is input, the controller 200 checks whether the hand free button is input for more than a preset time in step 419. If less than the predetermined time is input, the controller 200 proceeds to step 421 and releases the pause, that is, plays music again and returns to step 401. If more than the predetermined time is input, the controller 200 proceeds to step 423 to form a call path with the incoming call, that is, enters a call mode and ends the algorithm.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention.
